xml - Spring Boot logback-spring.xml

Question

有人可以帮我logback-spring.xml为这种情况创建一个文件：

启动日志和应用程序日志应记录到 2 个单独的文件中，这些文件会不断更新。文件附加程序将如何查看logback-spring.xml？

Answer 1

我设法通过这种方法实现：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="APP_FILE" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
        <evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
            <expression>return logger.equals("<YOUR FULL CLASS NAME FOR APPLICATION CLASS>");</expression>
        </evaluator>
        <OnMismatch>ACCEPT</OnMismatch>
        <OnMatch>DENY</OnMatch>
    </filter>

    <file>app.log</file>
    <append>true</append>
    <!-- set immediateFlush to false for much higher logging throughput -->
    <immediateFlush>true</immediateFlush>
    <encoder>
        <pattern>%d{dd-MM-yyyy HH:mm:ss.SSS} %magenta([%thread]) %highlight(%-5level) %logger{36}.%M - %msg%n</pattern>
    </encoder>
</appender>

<appender name="STARTUP_FILE" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
        <evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
            <expression>return logger.equals("<YOUR FULL CLASS NAME FOR APPLICATION CLASS>");</expression>
        </evaluator>
        <OnMismatch>DENY</OnMismatch>
        <OnMatch>ACCEPT</OnMatch>
    </filter>
    <file>startup.log</file>
    <append>true</append>
    <!-- set immediateFlush to false for much higher logging throughput -->
    <immediateFlush>true</immediateFlush>
    <encoder>
        <pattern>%d{dd-MM-yyyy HH:mm:ss.SSS} %magenta([%thread]) %highlight(%-5level) %logger{36}.%M - %msg%n</pattern>
    </encoder>
</appender>

<logger name="<YOUR PACKAGE HERE>" level="debug">
    <appender-ref ref="APP_FILE" />
</logger>

<root level="info">
    <appender-ref ref="STARTUP_FILE" />
</root>

只需更换：

<YOUR FULL CLASS NAME FOR APPLICATION CLASS>
<YOUR PACKAGE HERE>

例子：

com.bhrother.exampleapp.Application.class
com.bhrother.exampleapp

在这里，我们通过 loggerName 过滤日志以了解每个日志应该去哪里。
